Islander Bayport Automatic Dive Watch with Maroon Wave Dial #ISL-310

Islander is the watch brand of Long Island Watch, one of the most respected independent watch retailers in the enthusiast community. They design watches specifically for people who know what they want. They're well-spec'd, honestly priced, and built without compromise. We carry Islander because they represent exactly the kind of value that watch enthusiasts actually get excited about.

The Bayport is one of Islander's most refined diver designs, now in its third generation. This version brings partially skeletonized hands, a wave-patterned textured dial, and updated markers to a platform that was already hitting well above its price point. At 40mm with negative endlinks on the H-link bracelet, it's one of the most comfortable diving watches you'll put on at this size. The bracelet wraps naturally to the wrist without the endlinks flaring out, and the ratcheting micro-adjust clasp dials in the fit without tools. The 120-click unidirectional ceramic bezel and 200m water resistance mean this is a fully capable dive watch, not a diver-styled dress watch making do. All watches come with a 1 year warranty through Islander.

Our Take

Maroon is a bold call for a dive watch dial and the Bayport earns it. The wave texture gives the dial movement and depth that a flat surface can't match, and the maroon reads differently depending on the light. It's richer and darker indoors, more vibrant outside. The partially skeletonized hands are a nice third-generation upgrade that keeps the watch feeling contemporary without abandoning the tool watch ethos. What really sets the Bayport apart at $349 though is the bracelet. The H-link with negative endlinks and a ratcheting micro-adjust clasp is the kind of fitment solution that watches three times the price don't always bother with. On the wrist it feels thought-through in a way that budget dive watches rarely do. If you've been looking for a 40mm diver that splits the difference between too small and too large and comes on a bracelet that actually fits properly, the Bayport is a very easy recommendation.

Who This Watch Is For

• Dive watch buyers who've found 42-43mm too large and 38mm too small. 40mm is genuinely the sweet spot and the Bayport was built around that conviction
• Anyone who's been frustrated by dive watch bracelets that sit awkwardly on the wrist. The negative endlinks and ratcheting micro-adjust solve both the fit and comfort problems in one go
• Collectors who want a colorway that stands out from the navy and black dials that dominate the dive category. Maroon is distinctive without being impractical
• Buyers comparing this to the Babylon lineup: same Islander DNA, completely different mission. The Bayport is the one you take in the water, the Babylon is the one you wear every day
